Insulations today are rated by their (R) factor rating which doesn't tell the whole story. BTU loss is the best way to rank how good an insulation is going to be. Because Spray Foam Insulation eliminates air infiltration it can out perform traditional insulations by as much as 2.5 to 1. This is how the consumer can save up to 50% on their energy costs annually!!
